Depends on what you want to catch. You can fish in Trillium and the other lakes around hood, mostly for stocked trout, you can even check the stocking schedules online at the odfw site. I like to float tube them, not sure how good the bank fishing is, though I know Harriet Lake has decent bank fishing. Some of the small rivers offer fly fishing opportunities for small native cutthroat and if the time is right the salmon and steelhead will be running in the Sandy and Clackamas rivers.
